CUTTER-BAR ALINEMENT.

SPECIFICATION forming part of Letters Patent No. 753,459, dated March 1,1904.

Application filed November 16, 1903. Serial No. 181,457. (No model.)

1'0 wZZ whom, it may concern:

Be it known that I, GEORGE WILSON, a citizen of the United States,residing at Rockford, in the county of IVinnebago and State of Illinois,have invented certain new and useful Improvements in Cutter-BarAlinements, of which the following is a specification.

The object of this invention is to provide means for holding thefinger-bar in proper alinement with the cutterbar; and it consists inthe adjustment of that end of the couplingbar having a connectionwith'the main frame transverse to the length of the coupling-bar.

In the accompanying drawings, Figure 1 is aplan View of the cuttingapparatus of a mowing-machine. Fig. 2 is a section on dotted line a,Fig. 1. Fig. 3 is a section on dotted line Z), Fig. 1.

In the drawings I have shown only such portions of a mowing-machinenecessary to a complete understanding of my improvements, and in themain the parts are old. The bed has a forward projection 1, supportingthe crank-shaft 2 and crank-head 3. A push-bar 4 has a connection withthe under side of the bed at one end, and its other end has a connectionwith the yoke 5 of the cutting apparatus. This yoke has a connectionwith the finger-bar 6, also with one end of the couplingbar 7. A knife 8has the usual connection with the finger-bar, and a pitman 9 connects itwith the crank-head 3.

From the projection 10 of the bed extends a pin 11, upon which ismounted a collar 12, held in place by the bolt 13, supporting the washer14 and nut 15. The collar 12 has a rib 16, extending in its lengthwisedirection.

The coupling-bar 7 has one end provided with a split clamping-section18, adapted to receive the collar 12 and held in connection therewith bythe bolt 19.

The collar 12 is loosely mounted on the pin 11, and as thecoupling-barforms the connection between the finger-bar portion of thecutting apparatus and the main frame the cutting apparatus is free torise and fall.

By loosening the bolt 19 the end of the coupling-bar supporting thesplit clamping-section can be moved in the lengthwise direction of thecollar 12 toward the bed and clamped to the collar when adjusted.

The adjustment of the end of the couplingbar with the collar 12 willadvance the outer end of the finger-bar, the point of connection betweenthe push-bar and yoke acting as the pivot, thereby bringing thefinger-bar into proper adjustment with the knife in order to take up thewear.

The rib 16 of the collar 12 is located in the opening between the earsof the clamping-section in order that they may oscillate together, atthe same time permitting the clamping-section to move in the lengthwisedirection of the collar.

I claim as my invention 1. In a harvesting-machine, the combination ofthe bed of a machine, a projection extending from the bed, a finger-bar,and a coupling-bar forming a connection between the finger-bar andprojection, that end of the coupling-bar connected to the projectionmade adjustable in connection therewith in the lengthwise directionthereof.

2. In a harvesting-machine, the combination of the bed of the machine, afinger-bar. a

collar supported by the bed, and a coupling.

bar forming a connection between the fingerbar and collar, and madeadjustable in the lengthwise direction of the collar;

3. In a harvesting-machine, the combination of the bed of the machine, afinger-bar, a collar supported by the bed, and a couplingbar forming aconnection between the fingerbar and bed and made adjustable in thelengthwise direction of the collar, that end of the coupling-barconnected with the collar comprising a split clamping-section and aclamping-bolt.
